Safety hintsThe following instructions for
erection and use comprise de-
tailed information on handling
and use of the listed and depic-
ted products used in accordance
with the prescriptions.
The function-related instructions
stated in this assembly manual
have to be strictly obeyed to. De-
viations from this always require
a separate statical proof.
All nationally valid prescriptions
and regulations regarding safety
and health on construc-tion sites
have to be adhered to.
Safety regulations of the profes-
sional association and/or other
relevant authorities have to be
taken notice of, too.
Use only original parts supplied
by HÜNNEBECK which are in
an immaculate and undamaged
condition. Therefore, all com-
ponents have fi rst to be checked
visually to make sure that they
are from the HÜNNEBECK
company and are not damaged
before they will be installed.
Damaged parts have to be
sorted out and replaced by new
ones.
For repairs, only original parts
of HÜNNEBECK have to be
used as spare or replacement
parts.
Combined use of our temporary
edge protection system with
components from other manu-
facturers is a source of risk and
requires a careful check and
evaluation.
The technical details stated
within the scope of these ‘’In-
structions for Assembly and
Use“ are intended to enable the
user and/or erector to apply the
system in compliance with the
requirements included in the
‘’Order for Safety in Operation on
Site“.
The illustrations shown in this as-
sembly manual are to be under-
stood and regarded as examples
only.
They do not always include the
whole range of safety aspects
because it is easier in this way
to show the important details.
Nevertheless, all relevant safety
prescriptions that are valid for
safe work on site (UVV / Germa-
ny) have to be adhered to.
We explicitly reserve the right to
make changes or alterations in
the course of technical progress.
The latest version of the the ‘’In-
structions for Assembly and Use“
can be downloaded under
www.huennebeck.de via
internet or directly ordered at the
HÜNNEBECK company.

The basis of the wall formwork
is the H 20 timber beam. It is
produced in an electronically-
controlled production plant.
Wood quality and splicing is
continually checked, here.
The H 20 beam is sturdy, easy
to handle and at a weight of
only 5.0 kg/m offers a high
load-bearing capacity at large
distances of walers.
The advantage: fewer ties.
Due to the project orientated
arrangement of beams
and tie positions, an optimum
adaptation to ground
1.0 Product features
plans and to the demanded
concrete surface will be
achieved.
The steel walers (clamped
onto the H 20 timber beam)
allow the formwork elements
to be assembled quickly
and simply. The assembly is
done as easily as the
disassembly. The advantage:
no problems with the
restructuring of wall formwork
units when a frequent
change of ground plans takes
place.

economical alternative to the
project-independent formwork
systems. It is definitely
the best when it comes to
complicated ground plans
and to numerous uniform-type
applications with the
same wall heights.
The H 20 timber beams are
used for wall, column and
slab formwork. They show
high stability at low weight.
The H20 timber beam has a general approval of the
building authorities under the registration number:
No. Z-9.1-299 and is designed for the following statical
figures:
All safety regulations and
safety rules of local authorities
have to be considered for

6.0 Assembly of elements
4 Attaching the shuttering skinThe shuttering skin is attached with nails, srew nails, or screws
(preferably Spax screws). With its width of 8 cm, the H 20 beam
offers a firm base for nailing or screwing.
2 Positioning the steel walerson the assembly floor. Cams for cam walers or
traverses for steel walers are on the top.
3 Positioning the H 20 beamin the statically required spacing.
Attaching of the beams with H 20 timber beam clamps
(see also note below).
Attaching the H 20 beam to the steel waler with the
H 20 timber beam clamp.
1 For basic assemblyof the H 20 elements, an assembly floor which is large
enough for the largest element must be provided. To assure
the precise postioning of the walers and beams, stop bars
are nailed on. The stop bars are to correspond to the waler
spacing.
Preparation for assembly is the same for F-steel walers and for cam walers.

Fresh concrete pressure diagram
18.0 Technical data and load tables
General notes and explanations regarding the use of load
tables on page 31 and 32.
1. There are always three different figures of concrete pressure
(40, 50 and 60 kN/m²) for the execution of H 20 wall elements.
2. The wall heights of the elements are shown as static beam
systems with fixed arrangements of the walers (A, B, C, D, E).
All dimensions given in the load tables are actual distances
between the walers.
The initial height at the bottom is always 40 cm.
3. The execution of the H 20 wall elements defined with element
numbers between 1 and 41 is based on shuttering skin
(plywood) with 18 mm thickness (Modulus of elasticity is
assumed with appr. 700 kN/cm²).
4. There are 2 different figures to be found for the spacing of
H 20 beams, namely
a. determined by plywood 18 mm
b. determined by statical values of H 20
For the execution of elements, the smaller figures have
been taken into consideration.
5. The loading on the walers (A, B, C, etc.) are stated as
linear load [kN/m].
6. At the bottom of each load table, the relevant element numbers
(from 1 to 41) are shown. The element number depends on
the concrete pressure to be allowed and on the 9 different
element widths (B) which are based on the nine different
F-waler lengths (see page 31).
Notes and explanations with regard to the execution
of elements on page 33 and 34.
1. On page 33, all constructional details which are
important for the element design can be found (length
of walers, element widths, nos. of H 20 beams, exact
spacing of beams, etc.)
The fourth vertical column on page 24 contains the
element numbers between 1 and 41 which are also
given in the load tables. The arrangement of H 20
beams is based on the details shown at the bottom
on page 15 (item 4: attaching the shuttering skin).
2. From page 34 the typical arrangements of wall ties can
be taken (A, C, C/2, C1, C2, D, E) for each element
number. The tying schemes 1, 3 and 4 are fully
symmetrical.
When using tying scheme 2, pay attension to wall
elements of the same length B facing each other
bacause this tying is not symmetrical.
3. Tie rods D+W 15 mm dia. have to be applied for all
elements (perm. load F = 90 kN per wall tie).

21.0 Defined factors for calculations
Important features of the H 20 large-area formwork
5. Height extension
Wall elements can be extended at height by means of the H 20
extension butt straps. They are needed in pairs for individual
beams. Non-positive beam connections are assured in this
way.
Advantage: Use of elements for varying wall heights.
6. Versatility
The H 20 large-area formwork can also be used in conjunction
with climbing brackets and rigid support frames (single-sided
formwork) as well as for columns, tunnels and other types of
special formwork.
Advantage: Many-sided applications.
7. Additional components
All steel parts of the H 20 large-area formwork are hot-dip
galvanized.
Advantage: Clean components without rust. Long life-
expectancy of all steel parts.
8. Approval of H 20 beam
The H 20 timber beam has a general approval of the Building
Supervisory Board. It is registered under the No. Z-9.1-299.
Production of H 20 beams is continuously controlled.
Advantage: High safety due to constant quality of the product.
C. Weights
H 20 timber beam: approx. 5.0 kg/m
Steel waler: approx. 21.2 kg/m
Element: approx. 48.0 kg/m² without Ply
approx. 60.0 kg/m² with Ply
D. Time figures for erection / striking
Basic assembly: approx. 0.25 h/m²
Disassembly: approx. 0.15 h/m²
Erection and striking: approx. 0.30 - 0.50 h/m²
E. Transport volume of components
H 20 timber beams: approx. 0.022 m³/m
Steel walers: approx. 0.018 m³/m
Element without Ply: 0.24 - 0.31 m³/m² *)
Element with Ply: 0.33 - 0.38 m³/m² *)
*) dependent on method of loading
Defined factors for calculations
1. Basic assembly
The steel walers are fastened to the H 20 timber beams by
means of H 20 timber beam clamps. Fastening is possible at
any section of the steel walers.
Advantage: Quick and inevitable assembly and disassembly.
Safe connection.
2. Element connection
Adjacent elements are joined with waler connectors and
joining wedges.
Advantage: Connections are proof against tension and
compression, aligned and resistant against bending.
3. Adaptability
The variable adaptation of H 20 beams and steel walers
makes the flexible arrangement to any shape of ground plan
possible. The 165 cm long waler connector allows length
adjustments of up to 80 cm.
Advantage: Adequate adaptation to concrete pressure,
disturbing sections and adjustments.
4. Tying
Wall ties can be positioned accord. to statical requirements
or as required by the concrete structure itself. Page 34 shows
recommended tying schemes for standard elements.
Advantage: Disturbing sections can simply be solved.
